Italy’s Saipem has contracted BMT Scientific Marine Services (BMT) to provide riser monitoring systems for two Free Standing Risers (FSHRs) and four Steel Lazy Wave Risers (SLWRs) for the ultra-deepwater Sapinhoá Norte and Cernambi Sul pre-salt fields offshore Brazil.

The systems will monitor the integrity of the risers by measuring strains, motions, attitude, and position of submerged portions of the riser strings. Each FSHR system will include BMT’s patent pending ROV-Serviceable Strain Sensor Assembly, which allows users to service or replace individual sensors by ROV. BMT’s patented polypropylene welded attachment scheme for attaching strain sensors to submerged, insulated pipes will be employed on the SLWRs.

BMT has so far supplied five Free Standing Riser Integrity Monitoring Systems since 2007 covering a total of 12 riser towers, and two SCR monitoring Systems. The company’s order book includes integrity monitoring systems for three riser towers off West Africa and two off Brazil, as well as for eight SCRs in Brazil. In addition, BMT has in various stages of delivery six Marine Integrity Monitoring Systems for Floating Production Units, it added.
